I think smooth transitions from 3D scene to 3D scene are one of the great features in Proteopedia, and we should encourage using them. They allow the viewer to learn about different parts of a structure without losing their orientation.
Proposal: always transition smoothly
Keep the reload switch as is. If new coordinates are loaded (because they are new, or because reload is requested), switch directly to the new scene (no zoom no move).
Remove the other two switches, and always zoom out, show new scene, zoom in when the coordinates stay the same. If author wants to skip transition, they can turn reload switch on. If an author wants a different option, use JmolLinks to change orientation "by hand".
Demo: same coordinates
Start here:
Then transition with zoom out and zoom in:
Original delays:
Demo: new coordinates (or forced reload)
Start here: or here: .
Then load as fast as possible:
Original delays:
The two lines that make this slower:
delay 1.0;
moveto 1.0 { -506 -641 577 176.65} 707.57 0.0 0.0 ...
